ISR Performance o2 Housing for Top Mount SR20 Manifold

Built as a companion to ISR's SR20DET top mount manifold (part number IS-SSHT-NS13), this ISR Performance O2 housing routes the turbine outlet of a top mounted turbo down to the ISR SR20DET downpipe (part number IS-SSDP-NS13) on an S13 or S14 Nissan 240SX. Using the housing and downpipe together gives you a matched hot side instead of a pieced together one.

Flange details

The inlet is a 90mm Garrett style V-band flange, which suits many popular 28 and 30 frame turbos that use the Garrett 90mm V-band discharge. The supplied V-band clamp secures the housing to the turbine, and the three bolt outlet mates to the ISR downpipe with the included studs, nuts and gasket.

Check your turbo first

This housing only works with the Garrett 90mm V-band standard. It will not fit other manufacturers' V-band turbine housings or any other V-band size, so verify your turbine housing before ordering.

Fitment

• Nissan 240SX S13 and S14
• SR20DET engine with the ISR top mount manifold

What's in the box

• 1x stainless steel O2 housing for the top mount SR20DET manifold
• 1x V-band clamp
• 3x downpipe studs
• 3x downpipe nuts
• 1x three bolt downpipe gasket

Stainless construction holds up to the heat a top mount SR sees, and the V-band connection makes future turbo swaps a matter of releasing one clamp.
